I came across this paper because it is mentioned in the introduction of Aspinwall's lectures on D-Branes on Calabi-Yau Manifolds, where he writes in a footnote about D-branes that "The first reference to such objects that the author is aware of is, oddly enough, section 4 of [1]."
And indeed, on section 4 of the parody, there is an allusion to what we would call nowadays braneworld model-building, with the open string ending on a four-dimensional submanifold. So humour can be serious sometimes! After all the researcher's work isn't that different in its essence from a ludic fantasy...
